' I conramnnron STERILE *LIQUIDSd T 0 all wiwwt'it may concern:

Be it known that I, Gnsmr A. PrRssoN, a citizen of the United States of America, residing at 'Mount' Clemens, in the county of Macomb and State of Michigan, have in, vented certain'new and useful Improvements in Containers for Sterile Liquids, of which the following is a specification, reference a being had therein to the accompanying drawin -s.

This invention relates to a container designed to facilitate the ing of sterile liquids. g I The principal object-of the invention 1s to provide a device in which liquids in-' tended for hypodermic injection may be preserved in'an aseptic condition and from which doses maybe withdrawn-wlthout exposing the contents to infection.

' A further object of the inventionis to provide a container having a stopper of a material permitting the introduction ot a hypo-.

dermic needle therethr ough, whereby liquid may be'withdrawn from the conta1ner,means being provided for sterilizing the stopper and for maintaining t sterilized until the next Withdrawal between successive withdrawalsor" liquid.

A further object of the invention is to provide a stopper having. means by whlch a limited portionor" the contents of a container may be withdrawn from the main body of the liquid and held in position for ready withdrawal by a hypodermic needle without subjecting the portion so wlthdrawn to infection.

Other and further objects will appear in connection with the accompanying description, reference being had to the accompany ing drawing, in wh1cl 1 Figure lis a vertical section through a preferred embodiment of my invention, the protecting cap being shown in its closed position; v

Fig. 2 is a corresponding section illustrating the protecting cap partially open, with a portion ofthe liquid separated from the mainbody in position for withdrawal by the needle of a hypodermic syringe, and

Fig. 3 is an elevation of the device, the cap being completely closed. v

The device consists of three essentlal parts, a glass container 1, screw-threaded at its neck as indicated at 2, a hollow rubber stopper 3 and a metal protecting cap 4 screw storing and dispensthreaded to engage the neck offthe bottleas lndicated at 5.

tapered rubber stopper 3 'is provided of a1 Specification of Letters Patent. I .Pafientjed Mav 30,1922) I 7 Application filed November 5, 1921, Serial No. 513,214. i i i size to fit snugly within the neckof'thebots tle 1. The stopperJiiis madehollow, the

chamber '7 thereinhaving its outer portion beyond the neck of the i comparatively thin walls.

Inthe center of the base of stop er a circular opening 8. permitting liquldfto flow from the containerinto the bulbular 7 portion of the stopper 'w-hen the bottle'fis tilted upon its side. Ifth'ebottl'e' is coinpletely inverted, all the air within the stop per Wlll escape, thebulbular portionthen being completely filled Withliquid.

A glass ball9 acts as ayalve'preventing the liquidfrornflowing back into 'thegbottle' when the container is again placedinavertical position. The'screwcap 4.-"has a slot 10 formed withinthelscrew threaded portion thereof and when the cap is screwed down tight upon the bottle,xa shoulderll on cap engages tightly against the top or the bottle and thejslot 10 ,is' closed, since in this position of the cap theslot"lies'oppo site a portion of the glass neck. If the'screw cap is unscrewed, a portion of the thin walled:

bulbular part of the stopper will :be exposed opposite the slot 10, permitting a'yhypo dermic, needle 12 to be inserted through the rubher wall of the stopper'into theliquid on-1;

tainedv therein. By ,a proper ,manipulation of the syringeiand needle, sub stantially' the entire dose of liquid contained within' the;-"

stopper maybe withdrawn and when" the i needle is removed, the punctured rubber wall closes, completely sealing thei perforation made by the'needle.

Within the hemispherical topio f the cap isalayer of 'absorbentfelt saturated; with an antiseptic: material. Inthe act of.

screwing the cap into closed position andiir unscrewing the cap when arrang ng the container for removal. of a dose of the liquid,

this antiseptic pad of felt'will .b ebrou-ght into intimate contact withthe entire upper surface of the bulbular portion of the stop-' per, thus acting to sterilize the outer surface.

The operation of the device will be apparent from the above description; The bottle is first tilted to allow liquid to flow into the rubber stopper and if desired the container may be completelyinverted so that all the air within the stopper will pass out and when the bottle is tilted back into a vertical position the glass ball valve will seat itself within the port 8, leaving the bulbular portion of the stopper filled with the liquid.

The screw cap will'then be rotated to unscrew it from the neck of the bottle, the felt lining of the cap wiping the outer surface of the stopper with its antiseptic material and when the slotvlO is in a position opposite a part of thethin wall of the stopper which has not previously been punctured, a

' sterilehypodermic needle may be thrust through the rubber wall of the stopper and the liquid contained'therein may be withdrawn in part or altogether. The hypodermic, needle is then withdrawn; the screw I cap is again rotated to bring the antiseptic lining into close contact with the bulbular top of the stopper and to bring the slot opposite the glass neck.

be sterilized in any desired manner, or the sterilization 'may be' performed after the liquid has been placed within the container.

While the stopper has been described as made of rubber, it will be evident that an equivalent material may be substituted therefor. Such amaterial should be elastic so that a puncture will be closed upon the withdrawal of a needle and so that it will fit closely within'theneck of the bottle and it must resistthe heat necessary for the purpose of sterilization, while at the same time it must be without chemical effect upon any of the liquids used for injection.

It will thus be seen that there has been provided a device-possessing the particularlfeatures of advantage enumerated as desirable,

but which obviously is susceptible of modification in its form,-proportions and details of construction without departure from. the principle involved, or sacrificing of any of its advantages.

It will therefore be understood that the invention is not limited to the specific cletails shown and it is therefore claimed in any of its forms or modifications within the I claim: 1. A. device for dispensing sterile liquids COlIlPllSlIlg a conta1ner,'a stopper for the container consistingof a material adapted to permit the introduction therethrough of a hypodermic needle, and a stopperhaving an antiseptic lining therein in contact with said stopper when the cap is in closed position. I

2'. A device as in claim 1, in which the cap has a perforation freefrom the anticeptic' cap' for said container within said cap, said stopper being of a material permitting the introduction of a hypodermic needle therethrough, and said cap havlng an opening through a portion I thereof which lies opposite the neck of the container when the cap is in its closedposition, and which lies opposite a portion of the stopper when the cap is partially unscrewed.

4-. A, device for dispensing sterile liquids comprising a container, a hollow rubber stopper therefor, having a port communicating with the interior of the container and having a ball within its hollow interior adapted to be held by gravity to close said port and thereby to act as a valve to retain liquid within the hollow stopper, and a cap adapted to be attached to the container and having an antiseptic pad lining its interior of a configuration to engage the outer surface of the rubber stopper when the cap is terial capable of being punctured by a hypodermic needle, and a cover for said aseptic closure containing an antiseptic material in contact with said closure when thecover is in its closed position.

In testimony whereof I aflix my signature in presence of two witnesses.
